How do I serve a dynamically generated image in Django?
I have an html tag
<html>
...
<img src="images/dynamic_chart.png" />
...
</html>
linked up to this request handler, which creates an in-memory image
def chart(request):
img = Image.new("RGB", (300,300), "#FFFFFF")
data = [(i,randint(100,200)) for i in range(0,300,10)]
draw = ImageDraw.Draw(img)
draw.polygon(data, fill="#000000")
# now what?
return HttpResponse(output)
I also plan to change the requests to AJAX, and add some sort of caching mechanism, but my understanding is that wouldn't affect this part of the solution.
